We're dividing 55984780 by 251 
The aim is to understand the frequency of 251 in 55984780.

Going ahead to step 1:
If we divide 5 by 251, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 251

Moving on to step 2:
251 goes into 55 0 times with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Take the next digit (9) from the dividend and append it to 55, then repeat: 559 / 251

Advancing to step 3:
251 can be fit into 559 2 times, resulting in a remainder of 57.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 502 from 559 to get 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 251

Advancing to step 4:
578 divided by 251 is 2 with a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we take 502 away from 578, we end up with 76.
Fetch the next digit (4) from the dividend, attach it to 76 and continue: 764 / 251

On to step 5:
251 can be fit into 764 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 223.0
Subtract 753 from 764 to get 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 251

Advancing to step 6:
251 goes into 117 0 times with a remainder of 117.
Use 0 as the next digit of our solution. 
Result so far: 2230.0
If we subtract 0 from 117, we get 117.
Append the next digit (8) from the dividend to 117 and continue with: 1178 / 251

Let's proceed to step 7:
If we divide 1178 by 251, we get 4 and a remainder of 174.
Record the quotient 4 as the next digit in the result. 
Result so far: 22304.0
If we take 1004 away from 1178, we end up with 174.
Append the next digit (0) from the dividend to 174 and continue with: 1740 / 251

Moving on to step 8:
When dividing 1740 by 251, we get 6 with a remainder of 234.
Use 6 as the next digit of our solution. 
Result so far: 223046.0
If we subtract 1506 from 1740, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 9:
The number 251 fits into 2340 9 times, leaving a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 223046.9
If we take 2259 away from 2340, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 10:
251 can be fit into 810 3 times, resulting in a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 223046.93
The remainder is 57 after subtracting 753 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 11:
When dividing 570 by 251, we get 2 with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 223046.932
If we take 502 away from 570, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 12:
680 divided by 251 is 2 with a remainder of 178.
The number 2 becomes the next digit in our result. 
Result so far: 223046.9322
Subtracting 502 from 680 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Our division results in 223046.9322 with a remaining 0.00178.
